Patent ed April 2, 1907;

Application filed February 20,1906. Serial No. 802.054.

State of Pennsylvania, have invented certain 'new and useful Improvements in Flarin- Machines for Metal Rings, &c.; and l o hereby'declare the following to be a full, clear, and exact description ot the invention,

to such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafterdescrihed, reference being had to the accompanying drawings which illustrate r 5' one form in which I have contemplated e1nbodying my invention, and said invention is fully disclosed in the following description {and claims.

1-; -Referring to the said drawings, Figure 1 a no l'e piesents a side elevation of an apparatus embodying my present invention.

Fig. 2 represents a vertical central longitudinal section of the same, certain portions being shown in elevation. Fig. 3 is a front view of Fig. 4 is an enlarged View of a portion of the front of the machine, showing the operation of the parts in flaring the ends of a metal ring or tube. Fig. 5 is a top lan view of the upper and lower flaring-re lers pprtions of the machine. Fig. 6 is a top plan vlew of the front and rear guiding devices for steadying the upper portions of the rings while they are being operated upon.

5 is a perspective view of a metal ring d g-- signe to form the middle ring of a pipe cou lingas it appears before being subjected to t e action of this machine. Fig. 8 is t similar VIBW of the same ring after it has been 0 subjected to the action of the herein-do scribed flaring-machine. Figs. 9 and 10 are detail perspective views of the upper and lower flaring-rolls, respectively, showing the parts thereof separated.

5 The object of my invention is to provide a machine for flaring or bending outwardly the 1 marginal or other portions of a metal ring or section of tubing, and the parti cular machine 'yherein shown and desoiibed' and which emo bodies-my invention is particularly designed is formed by cutting a skelp of iron idin -rollcrs and ad'acent or steel, preferably steel, having a central longitudinal rib orhead on one face, into sections or blanks oi" the required length to produce a ring of certain size, bending the blank into the form of a ring with the head on the inner side and welding the two ends of the blank together, after which the ring is sub jected to the action of the flaring-machine herein shown and d= :ribed, in which. the al portions ad acent to each end or edge of the ring are simultaneously flared out 'ardly for the purpose of hunting a packin g-reccss to'receivc a suitable rubber or other elastic peeking when the ring is used with the other parts forming a Dresser coupling.

In Fig. 7 i have shown one oi the rings A as it appears after being welded and. before being subjected to the action. of the flaringmachine, the said ring being provided witha central internal web or rib a, as shown. It is to be understood, however, that my invention applicable to machines for flaring the ends of rings or tube-sections which have no internal bead and that the form of tho fin ished ring, as dolined by the flared portions thereof, may be varied to a -onsi .l0rablo extent to suit dill'eront requirements by varying the configuration of the flaring-rollers hereinafter described.

lelcrring now to the generalconstruction of the machine, 13 repres-onis thclmse-plate, upon which are secured lhed'orward Vertical standard (5 and the rearward vertical stand Md (1.

i) represents the lower roll-shalt, which is horizontally disposed and is mounted in .lixed. hearings in the standards C C. At the front end of the machine the shaft D is provided with a reduced portion (1, which re ceives the lower or outer flaring-roller, which is secured on the shaft by a suitable nut (1, so that the said roller can be removed and replaced when desired. At its rear end the shaft 1) isprovidcd with a driving-gear D engaging a pinion E on a driying-shaft E, mounted in bearings in the standard C and in a separate standard C or bearing-sup ort, and said shaft is providedwith the usuai fast and loose pulleys E E, by means of which the machine is driven. The shaft 1) is also provided (preferably between the standards C and O) with a pinion D as shown. q

The parts can. oo a-coursitely adjusted by means oi the scroii sliaft m which mm also he so j usliocl from time to time to oomp ensote for any we. r of the parts. The particular irioolionism for dooress'ing the swinging s mill I lilo/rein shown nntldso i; of my '9 illiistrn cnivcl :1? ilio iin'nui' and of lllO rooess c in sinnrlnrrl l and ll'fivlilfll Will) a hollow iiilw'l corn or linslinig Z, Wlllfll extends jet-ting flanges at, having curved slots n therein concentric with the axis ofst ud n. These brackets are held in ad pisted position i by means of bolts n extending through the slots n and provided with nuts, or capscrews may be employed, if desired. In the upper end of each of said brackets N is mounted an idle roller 71:, provided with an annular flange at each end for guiding and supporting the rings during the operation of the flaringi'olls.

in order to steady the upper parts rings, especially when rings of large dian'ieter are being operated upon, I prefer to provide suital guiding devices for engaging the peri "ral edges of the rings as they are rotated by the flaring-rolls. For this purpose l have shown two different forms of guiding devices, and I prefer to employ both forms in the n'ianncr shown'; but it.is to be understood that l may use two guides constructed alike or vary the relative arrangcmtmt of the guides, if desired. in the present instance I have shown at the left of the machine viewed from the front a bracl-tet-arm p, secured to the standard (I and carrying at its end a forwardly-cxtending stud 7). (See Figs. 2, 3, t. and (5.) An angular bracket 11 is secured to the right-hand side of the standard C and has a forwardly-extending arm 72 in which are provided two guiding-recesses p and 77".

i represents the rear guide, which is pivotally mounted on the stud 7) between nuts on a threaded portion of the shaft, thus providing for slight lateral adjustment of the guide, and said guide has vertically-disposed "aces for engaging the edges of the rings and i:- urved or arched centrally to engage the rearward portion of the upper flaring-roll, with which it rises and descends. The free end of guide l. is arranged to. drop into the recess in the arm 7) when the rolls are in -;pcralive relation, so that both ends of the guide are 'icld firmly and the guide will steadv the ring on its rear e ge as it is roiatcdi 'lhc front guide may be similarly formed; but l prefer to en'iploy the guide l, which c nsists of a shaft 71", connected to the s: ad p by an universal joint so that it an be wung out. of the way to l'acililate the introduction and removal of the rings. 'l'he shaft p is provided with two long rollers p, which engage the edges of rings of dill'ercnt diameters, and the free end of shaft. 71" is adapted to engage the notch or recess 1 when in operative position. l have found. hat with these guiding devices. are de irable io stcadr the upper anxious of the larger" sizes of rings; but for the smaller sizes they are not necessary and may be dispensed with.

Q represents a belt-shifter pivoted upon the base of the machine andconnected to a sliding shifter-bar guided in a. bracket secured to standard (1" and provided withv belt-engaging arms q q for shifting the driving-beltfrpgu the fast to the loose pulley.

'In using theepparatus herein shown and described the rings to be flared are raised to 75 red heat, and the roll GI being in raised posi tion one of the rings is placed upon the roller 1) and lateral guide-rollers.- The. machine may be. driven continuously, or the belt-shipper lever may be operated at intervals to start and; stop the machine. I prefer, however, to Having the flaring-rolls operate continuously. 'lhe flaring-rolls being in continuous rotation the lever m is given a quarter-turn to force the inner or upper roll down upon the inner face of the ring. As soon as the ring is gripped between the two flaring- 'Iolls it will begin to rotate about its axis, andas the pressure upon the lever m continues i 'to bear down upon the upper roll the inclined o shoulders thereof will flare outwardly the edge or margi ial portions of the ring until they are forced into contact with the inclined sl ulders (Pct-the lower roll. One or two rt ilutions of the ring between the upper and lo. cr flaring-rolls will flare both ends of the ring simultaneously and accurately. 'lhc lever m is then reversed, theupper roll allowed to rise under the influence of its counterbalance and the ring may be removed and another substituted, when the operation-will be repeated. in Fig 8 I have shown the'ring A is it appears after being operated upon by this machine, and it will be seen that it is provided at each end with a flange or flared portiorta'.

It is to be understood that when the front guide P is employed it is necessary to lift its free end out of the notch 1f and swing it out of the way to remove the rings from the'machino and to replace it after each ring is inserted.

The shape of the flared portions (1/ a of the ring A will depend upon the form of the l)ev cled portions or shoulders g and d of the m5 flaring-rolls, and these shoulders may be varied in shape to produce flanges of various ,:ross-secti 'ms, as l'nay be desired. ft is also' obvious that in handling rings which do not have a central bead the groove in one of the 120 flaring-Millers which accommodate said bead (in this instance the upper or inner roll) may be dispensed with.

What I claim, and desire to secure by Letters Patent, is 12 5 l.
